recordings with M-Audio MobilePre

As noted in an earlier post, the M-Audio MobilePre is an el-cheapo USB preamp interface. But I had to rely on that for some trial recordings.

Using a Maxim mic, laptop sound card noise floor is around -50 dB

M-Audio MobilePre with Maxim mic noise floor is around -60 dB

Using dynamic mic - Ahuja ASM-780XLR - results were similar.

Nose floor rises to -40 dB when capture slider increased to 80%.

The XLR input on the MobilePre seems to be defective - S/N almost unity! -18 dB of noise
